Embodiment Construction

[0019] In order to clearly understand the technical content of the present invention, the following examples are given.

[0020] The specific steps of this method are as follows:

[0021] Step 1: Obtain STL format files;

[0022] Put the STL file of the color model to be printed into the slicing software;

[0023] Step 2: Obtain the triangular surface and calculate the projection;

[0024] The slicing software obtains the triangular faces in the STL file, and calculates the projection of the triangular faces on the X / Y plane through the three-point coordinates of each triangular face;

[0025] Step three, screening projections;

[0026] Screen the projection of the triangle surface on the X / Y plane with the angle between the triangle surface and the X / Y plane not equal to 90°;

[0027] Step four, get the path;

[0028] Convert the filtered projection into a path, that is, the path between the coordinates of the starting position of the projection and the coordinates of the ending position, ...

Abstract

The invention discloses a color spraying method based on a colorful 3D printer. The color spraying method comprises the following steps that firstly, an STL format file is acquired; secondly, triangular faces are acquired, and projections are calculated; thirdly, the projections are screened; fourthly, paths are obtained; and fifthly, color spraying is carried out according to the paths. The colorspraying method has the beneficial effect of solving the problem that spraying is incomplete when the gradient of the contour line of a model is gentle.

Description

Technical field [0001] The invention relates to the technical field of 3D printing, in particular to a color spraying method based on a color 3D printer. Background technique [0002] 3D printer is a kind of cumulative manufacturing technology, namely a kind of machine of rapid prototyping technology. The working principle of a 3D printer is to put the data and raw materials in the 3D printer, and the printer prints the model to be printed layer by layer according to the program. The color 3D printer is based on the ordinary FDM 3D printer, and sprays the color of the printed model to obtain a color model; currently there are color 3D printers on the market that do not calculate the edge of the model when spraying the model, especially the model surface slope In slower places, incomplete spraying appeared, resulting in low precision of color spraying on the surface of the model and unsightly appearance. [0003] Therefore, a method is needed to solve the above problems. Summary ...
